TO ALL WHOM IT MAY CONCERN:

Be it known that I, DpNIEL R. PRATT, of Worcester, in the county ofWorcester, and State of Massa.: chusetts, have invented a new andimproved Pin for securing wearing apparel; andI do hereby declare thatthe following is a full and exact description thereof,v referencebeingbad to the accompanying drawings and to thc letters of referencenmrled thereon.

The nature of my invelition consists in making the common wearingapparel piii with a corrugated body, so as to stiffen the wire of thepin and to prevent it from being worked out of any articles secured bythem.

To enable others skilled in the art to mnke and use my invention, I willprofeeed to describe its conbe secured, ns the contortionp are onparallel lines in rising and falling, giving support to eachotheralternately, thereby strengthening the bbdy of the pin, as shown et fig.1 and fig; 2 in thedrawingsrhercwith presented. The corrugntions may belcit off near the points and end near the heed to prevcnttheir beintroublesome in being pnt through any `fabric in` .whiehfflthe moaheearnclosely-and-Stlllly'united, b\1ft=whenl this'isdonc tireistrzzighfpurtsv of the body f thcpin must be brought to n. central lineof the corrugations, so that the pin will be guided strnight through anyfabric or article to he secured by them, und the straight parts willallow the fabric t-o .relieve itself by contracting or expanding of thewrinkled or contorted folds ofthe fabric on the smooth and straightparts of the pin, und will start much easier when it is desired toremove them from any fabric secured hy them. It will he seen that amilch shorter pin will hold any article if it is corrugated or contortedinto folds on a pin that is corrugated than one where the fabric -ismerely contorteil into folds ou a smooth pin. The dif ference oi'security of two pins of equal length will be nearly two to one in fni'orofthe corrugated pin; consequently, a great saving in articles lo'st bythe use o f smooth pins, while my improvement will prevent the loss ofmillions of those little agents called pins, useful to the comfort andadornment of mankind.

I alnvawsrc that hair-pins of two prongsv have been made in spiral form,or otherwise outl of a, straight line. I am aware, also, that {inc pins,bearing ornaments` have been made in spiral form. I claim neither ofthese. A hair-pin without head 0r point cannot be used in cloth or otherfabrics. i A spring, made spiral or with e screw-thread upouit, canbeinserted or withdrawn only by means of a definitive rotation.

My pin is, in the rst plsu-,the simple and common pin for securingclothing and articlesof wearing apparel, and, as nn article ofmanufacture, it cannot conflict with a haippin. It'is turned from ostraight line, not sph-ally, end'so as to require rotation in use, butby regular corrugationsor liexures, so as to holdmore tcnuciously than ostraight pin, and possesses greater'stre'ngtli, and isfsecure fromfalling out; and yet itis susceptible of being removed withoutV violenceto the fabric; l *Y what I claim as my iilventiomind desire-to secureby'LettersPatengis- A common pin for Aclothingor wearing apparel Vturnedfrom a straight line by corrugatos or exures, as
